Can't shrink volume more than 175GB?

[Argyron]

I have a 1TB hard drive that I started to shrink because I wanted to create a linux partition. I started shrinking 300GB out of the 500GB free space but after around 20mins there was a black out in my house (first world problems).

So I waited for the power to come back and there is a dskchk when I turn the pc back on. I go to make another partition and it says I can only shrink a maximum of 178.7GB. It says something about defragging so I used Defraggler but I'm still getting the same problem.

Any ideas?

I remembered about Gparted and used that but thanks anyways!
